Ready-Mix Concrete
Batched to specification and delivered fresh in transit mixers — with the grades, slump, testing and paperwork your engineer expects.
Grades
Concrete grades and where they are used
| Grade | Typical use | Notes |
|---|---|---|
| C15 / Class 15 | Blinding, mass fill, non-structural bases | Nominal mix, unreinforced work |
| C20 / Class 20 | Ground slabs, foundations, light structural work | Common domestic grade |
| C25 / Class 25 | Suspended slabs, columns, beams, ring beams | Most requested structural grade |
| C30 / Class 30 | Heavy-duty slabs, driveways, water-retaining work | Designed mix |
| C35 and above | Bridge decks, industrial floors, precast structural units | Designed mix, on request |
Final mix design is confirmed against your structural engineer's specification before batching. Where a designed mix is required, send the specification with your enquiry.
Technical
Supply, delivery and testing
Mix options
Nominal or designed mixes; sulphate-resistant cement, plasticiser, retarder, waterproofing and pumping admixtures available on request.
Slump
Typically 50–100 mm for standard placement and 100–150 mm for pumped or congested-reinforcement pours. State the required slump on order.
Minimum order
Part loads are accepted, but a short-load charge applies below a full truck. Confirm the current minimum with the sales desk when booking.
Truck capacity
Transit mixers are loaded per truck to the volume confirmed at booking; large pours are sequenced across multiple loads to avoid cold joints.
Delivery radius
Nakuru town and the surrounding county as standard, with wider Rift Valley deliveries quoted per site. Access, gradient and turning space are checked before dispatch.
Lead time
Book ahead of the pour date. Same-week slots are usually possible; large or early-morning pours should be confirmed in advance.
Testing
Slump testing at discharge and cube sampling for 7-day and 28-day compressive strength, with results issued against your delivery reference.
Pumping
Pumping is arranged through partner plant where a site needs it. Tell us the pour height and distance and we will confirm availability with the quote.
Documentation
Every load is delivered with a batch/delivery ticket recording grade, volume, time of batching and mix details for your records and the engineer's file.
